Amid mounting speculation that Pakistan cricket coach Bob Woolmer was murdered in his hotel room in Kingston, Jamaica, five days ago, Jamaican Police on Thursday called in Scotland Yard specialists to help investigate his death.

A senior detective from Scotland Yard is already in the Caribbean to liaise with the Jamaican police, which said on Wednesday that the 58-year-old former England Test cricketer's death was "suspicious" and required "full investigation".

Woolmer was found dead in his 12th floor room in Pegasus Hotel on Sunday within hours of Pakistan's shocking defeat at the hands of Ireland, which led to their exit from the World Cup and subsequent retirement of skipper Inzamam-ul Haq from one-day cricket.

Suspicions that Woolmer was murdered were strengthened with police sources saying that a bone in his neck had been broken, indicating that he may have been strangled in his hotel room.

In the absence of an authentic word on the cause of the sensational death of the coach, Jamaican media quoted police sources as saying that fresh evidence suggested that Woolmer was strangled in his room.

"A high-ranking police officer confirmed that fresh evidence has surfaced, suggesting that Woolmer was strangled in his room at the Jamaica Pegasus Hotel between Saturday night and Sunday morning," a newspaper report said.

"A bone in the neck, near the glands, was broken and this suggests that somebody might have put some pressure on it," a report in Jamaica Gleaner said.
